To all whom it may concern:

Be it known that I, WALTER P. MURPHY,

i a citizenof the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new and- 'useful Improvements in Corrugated-Sheet- Metal End Structures for Railway-Cars, of

Having inview particularly the hard usage to which the ends of freight box' cars are; subject due to shifting, cargoes and. like causes, cars of this sort have been equipped,

Fig. 6 is a view, in perspective, of theupper attaching and rigidifying b which may be employed as part of either of the two constructions shown in the preceding figures, and

Fig. 7 is a similar view of the bottom attaching member.

Like characters of reference designate like parts in the several figures of the" drawings. v The car end is shown for purposes of illustration as applied to a wooden box car of standard -construction. The wooden end plate of the car framing is designated 10, the end sill 11 and the corner post's'12. 13 indicates the roof, lt the end fascia and 15 the flooring of the car.

The end structure shown in Figs. 1 to 3 inclusive is composed of a corrugated panel consisting of two sheet metal elements 16,- an upper rigidifying and attaching member or metal end plate element 17 (Fig. 6) and a lower angular rigidifying and strengthenfmgmember'lS (Fig. 7). The end sheetslG, 216 are formed with vertical corrugations 19 which extend across the sheets fromtop to bottom, that is, from the upper end to the lower edges thereof.- The sheets are formed on their outer laterahedges, with angular flanges 20 which are secured to the corner posts ,12 by any suitable means, for example,

plate Patented 0011.30, 191 a 5 the "bolts 21.- The meeting edges of V the sheets 16 are preferably provided with angularly disposed flanges 9.2 fastened together byrivets 23, The top member or metal end plate 17 is secured to the wooden end plate 10 by bolts 24, or other suitable attaching devices and has flanges 17 b (Fig.6) overlapping and secured to the sidewall of the car. The lower edge of the top. member overlaps the upper edge of the panel 16, 16 and has a corruv gated or undulatory configuration correspending with the corrugated configuration on horizontal lines. .20

of the panel. The panel and top member 'bolts 27, and an upstanding flange 28 which is corrugated or given an undulatory configuration t'o fit the corrugations of the panel 16, 16. Preferably the upstanding flange 28 is arranged on the inside of the panel, the latter being secured theretoby rivets :29. In order to make the car grain proof the horizontal flange 26 of the bottom member extends'preferably under the flooring 15. Y

In Figs. 1 and 5 I have shown a modification in which the panel is divided into two sheets (there might be. more, if desired) The construction consists, in addition to the top and bottom pieces which may be substantially the same as those employed in the first described construction, of two sheets 3.0, 31, extending across the car from side to side and formed with corrugations which, in each case, extend from one edge of the sheet to the other. The upper sheet overlaps the under sheet and is secured thereto by rivets 32. The top member, designated 17*, overlaps the upper edge of the upper sheet 30. The bottom member 18 is overlappedby the lower edge of the lower sheet 31 as in the other construction.

In both typical embodiments of the invention a car end is provided having corrugations extending, inv efl'e'ct, fromthe roof to the floor of the car so as to form load bearing elements capable of carrying some of the weight of the roof. Moreover, these corrugations, because of their vertical, ar-

" rangement, materially strengthen and stiffen the end as against the tendency of the car to weave, that is, to become distorted on diagonal lines. The construction, in each case, is waterproof.

A sheet metal car end constructed as shown and described, besides having the structural advantages noted can be very cheaply manufactured. The ordinary corrugated' sheet metal car ends in which the eration are expensive because of their large size and are easily broken because of the weight of the sheets of metal on which they operate. Moreover, the pressing tends to thin out the metal of the sheets at certain places, making the end structures weaker in some places than in others. Besides this the sheets in pressing are considerably distorted so that they have to be trimmed;

with corrugations extending from one edge to the other the corrugating operation may be performed in an ordinary 'corrugating machine by a continuous process and in some cases without heating the metal. There is no tendency to thin down any part of the sheet. The corrugating operation is very much simplified and cheapened. If sheets so formed were used without the top and bottom members 17, 18, that is, if there were fastened directly to the framing of the car along their top and bottom edges, the structure would have little or no strength to resist deflection. It would bend on lines parallel to the corrugations. It will be seen that the top and bottom members 17, 18, provide, in the first place, a rigid reinforcement extending in a direction transverse to the corrugations so that deflection by the pressing out of the corrugations which would otherwise take ,place when the end was subjected to a heavy cargo thrust, is effectually prevented.

Each corrugation acts as a post orupright beam transmitting stresses, such as the thrusts of the lading to the upper and lower edges of the sheet. In the construction described the metal end plate or top member 17 takes the stresses thus transmitted to the, upper edges of the sheet or sheets and carries them to the side frame members of the car. In effect, the corrugations extend over upon the metal end plate, although this is not essential to the function in question. With a vertically corrugated end it is important that the upper edges of the sheet or sheets be thus provided with means for taking the stresses of the corrugations and transmitting them to the side walls of the car, since the roof of a box car is ordinarily the weakest part of the structure and is little calculated to take the heavy stresses resulting from shifting cargoes. It is also important that the lower edge of a vertically corrugated end sheet be provided-with a transversely extending rigidifying member capable of taking the stresses from the corrugations and transmitting them to the car frame, because, while the end sill is more capable of taking the stresses on the corrugation than the roof of the car, ordinarily the against it. directly to the corner posts and In the end wallconside walls of the car. struction described, each'corrugation preferably merges into the next, so that the structure has 'a sinuous configuration in cross-section. As -a result, end stresses against the corrugation are transmitted in part'to the adjacent corrugationswith the result that undue deflection at any given point or along any given line which might result in rupture of the metal is avoided. Moreover, the top and bottom members provide a convenient means for attaching the corrugated sheets to 1 the upper and lower frame members of the car. The structure at these places is perfectly water- -proof.' The angular configuration of the bottom piece 18 makes the end structure tight at the flooring of the car. This is important as boX cars are used very extenvelyfor carrying grain.

VhileI have described my invention in in preferred embodiments, modifications might be made without departing from the principle of the invention. Therefore, I do not wish to be understood as limiting the invention to the precise constructions, arrangements and devices shown and described except so far the claims are so limited by their express language.

This application is division of my copen'ding application No. 733,369 filed November 25, 1912. a The subjectmatters comanon to the two applications are claimed in application Serial No. 182,767, filed July 23rd, 1917, as a continuation in part of the aforesaid application 733,369. I do not claim. specifically the construction shown herein in Figs. .1, 2 and 3, as this construction-was-made the subject of another divisional application, -Serial No 1979 filed January 13, 1915, this applicatlon covering, however, the invention common to both the modifications herein shown and described.
